To synthesize speciality oligomers, one of the controlled / living free radical polymerization, RAFT polymerization was used. As reaction media, Supercritical carbondioxide, which has tunable solvent-power was used. In order to do this research, Supercritical experiment equipments were designed. Additionally, the RAFT agent, Cumyl dithiobenzoate was synthesized for RAFT polymerization. Methyl methacrylate and AIBN were used as monomer and initiator. As a result, the Mn and PDI was verified as numerical value of around 5,500 and 1.2, depending on the variation of reactans mole-ratio, reaction time, and CO2vol.%. |
